that all depends on the person behind the trigger. a pull of the trigger doesnt always = death. however, if your life (or your family or friends life) is in danger from someone with a gun or other dangerous weapon, you will wish you had a tool to stop that person. a gun can be that tool.

No, toasters don't toast toast, but neither does toast toast toast. People toast toast. People are living creatures capable of thought and therefore are the reason that toast is toasted via a toaster, and are also capable of killing people. A guns purpose is to kill, but the gun doesn't kill anyone. It is incapable of doing so because it is an inanimate object incapable of any sort of action. The person has to pull the trigger and kill the other person, but if you want to blame the gun that is fine I'm sure the gun will learn its lesson in jail.
